To be serious though, I think we can learn a lot from tarantulas. If they don't need anything, they don't do anything. And because of their simple brains, they can't really want anything they don't need. Since we give them just about everything they need in captivity, they end up spending most of their time just ... existing. It's a hard thing for a human to do, since we have so many thoughts and worries and wants and feelings.
